Water exercises: Dive in!

Float upright in deep end. Bend knees and quickly swivel feet in opposite directions while making small circles with cupped hands in front of you (as shown). Continue for one minute. Rest 30 seconds; repeat up to three times.

Technique tip Water polo players rely on this maneuver to stay afloat. The faster you move your feet, the higher you'll drive yourself out of the water. Try using only legs and hold arms overhead.
